Title: Test circuit for semiconductor memory
Inventor: RII RIAN SHIYUU
IPC: G01R31/28
Filed: 1993-09-08
Abstract: PURPOSE: To provide two current detection differential amplifiers together with a testing circuit for testing entire rows along one word line and to simultaneously test entire rows of memory array without adding a sense amplifier. CONSTITUTION: When every cell correctly stores logic 1, current does not flow to a teat line TL, and the current which is equal to a product acquired from current derived by a single memory cell and the number of accessed memory cells flows to a complementary test line TLB. When current does not exist in the line TL, an output of a 1st differential amplifier 10 becomes low, and when current exists in the line TLB, an output of a 2nd differential amplifier 12 becomes high. A comparator 14 detects two opposite logic states of logical value of the test amplifiers 10 and 12 and outputs value of the logic 1 which shows that appropriate data is stored in memory cell. This means that the test result for entire memory cells along the word line is satisfactory.

Title: Microwave electric-discharge light source
Inventor: YADA MASAAKI
IPC: H01J65/04
Filed: 1984-10-25
Abstract: PURPOSE:To minimize the nonuniformity of the emission of an electrodeless lamp by installing a planar microwave-transmitting member for equalizing the intensity distribution of microwaves directing toward the electrodeless lamp in a microwave cavity resonator in which the electrodeless lamp is installed. CONSTITUTION:Between a straight tubular electrodeless lamp 23 and the antenna 16 of a magnetron 11 in a cavity resonator 18, a microwave-transmitting member 26 is installed which disperses microwaves radially discharged from the antenna 16 to equalize their intensity distribution. The member 26 consists of a planar metallic net 27 and is installed parallel to the opening 19 of the cavity resonator 18. The microwaves from the antenna 16 are directly discharged into the cavity resonator 18 in which the electrodeless lamp 23 is installed. These microwaves are then widely dispersed by the member 26 to make microwaves to be almost homogeneously applied to the entire surface of the lamp 23. As a result, the entire lamp 23 homogeneously emits light and the nonuniformity of the emission can be minimized.

IPC: B22D19/14
Filed: 1989-08-31
Abstract: PURPOSE:To manufacture the silicon carbide-contg. alloy in which silicon carbide powder is handily and uniformly dispersed in a finely powdered state to a high degree by pulverizing the flocculated part in silicon carbide powder, restoring the part into a state before flocculated and dispersing it into a molten metal. CONSTITUTION:In an air flow pulverizer 4, the material powder P of silicon carbide is fed to a pulverizing part 46 from a raw material feeding part 4a via an inert gas as a carrier gas. In the pulverizing part 46, the above material powder P is pulverized by a pulverizer such as a jet mill. In this way, the flocculated part in the material powder P is restored into the state of primary grains before flocculated. The average grain size of the primary grains in the silicon carbide before flocculated is preferably regulated to <=1.0mum. On the other hand, a metal M melted by a heating apparatus 2 is charged to a dispersion vessel 1 arranged in an inert gas atmosphere. The above material powder P transformed into the primary grains is introduced into the metal M in the molten state together with the carrier gas via an introducing pipe 5, which is furthermore stirred and mixed by a high frequency stirrer 3. In this way, the silicon carbide powder is uniformly dispersed into the molten metal M, which is thereafter cooled and solidified to obtain the silicon carbide-contg. alloy excellent in the capacity such as strength.

Title: Squid protecting device
Inventor: KIDO TERUO
IPC: G01R33/035
Filed: 1991-08-10
Abstract: PURPOSE:To effectively prevent damage of a SQUID by connecting at least one Josephson junction in series with the SQUID. CONSTITUTION:Since a SQUID and JJ3 are operated in a normal using state in which an overvoltage is not applied, in a range that a resistance is '0', a voltage to be decided based on SQUID voltage output characteristic in a magnetic flux to be introduced into a superconducting loop 1, is output. Accordingly, an external magnetic flux can be measured with high sensitivity by cancelling a variation in the magnetic flux to be introduced to the loop 1 by supplying the output voltage to a magnetic flux locking loop. If the overvoltage is applied, the applied voltage to the JJ3 exceeds the range of '0' resistance, the JJ3 becomes a voltage state to have a resistance. Thus, a voltage drop due to the JJ3 occurs, the fact that the applied voltage to JJ2 of the SQUID becoming excessive can be effectively prevented, and damage due to the overvoltage of the SQUID can be effectively prevented.

Title: Diagnosing method for rejection at organ-transplanting time
Inventor: MARUO NAOKO
IPC: G01N33/53
Filed: 1992-08-04
Abstract: PURPOSE:To diagnose the possibility of rejection at organ-transplanting time by measuring the concentration of interleukin (IL)-6 receptor in bio-sample collected from an organ-transplanted patient. CONSTITUTION:The blood serum in which the soluble IL-6 receptor most abundantly exists is used as a bio-sample. The measurement of the IL-6 receptor is carried out in such a way that the bio-sample is brought into contact with an anti-soluble IL-6 receptor bonded to a fixed supporting body so that the soluble IL-6 receptor in the sample can be bonded to the anti-soluble IL-6 receptor and another antibody bonded to a labeling substance is brought into contact with and bonded to the soluble IL-6 receptor. In addition, a monoclonal antibody is used as the antibody in order to perform highly accurate measurement in a short time. While rejection diagnosis can be performed by measuring the concentration of the soluble IL-6 receptor, it is preferable to subject the bio- sample to IL-6 concentration measuring operation and relate the sample to the measured concentrations of the soluble IL-6 receptor and IL-6 so as to make the rejection clearly distinctive from infected diseases, etc.
